Mechanical seal manufacturer Installation and use requirements

1) The pump must be selected according to the working conditions and the main engine Light mechanical seal The proper type of mechanical seal shall be matched with the material to ensure the normal operation and service life of the mechanical seal.

2) Pump for installing shaft (sleeve) at mechanical seal Medium mechanical seal The radial runout tolerance shall be ≤ 0.04mm, and the axial runout of the rotor shall be ≤ 0.1mm.

3) Install the seal end cover (or housing) of the mechanical seal stationary ring, and the perpendicularity of the positioning end face to the shaft is ≤ 0.04mm.

4) During the installation of mechanical seal, the shaft (shaft sleeve), seal chamber, seal end cover and mechanical seal itself must be cleaned to prevent any impurities from entering the sealing part.

5) When the temperature of the conveying medium is too high or too low, or contains impurities, particles, inflammables, and is prone to explosion and toxicity of the mechanical seal used for slurry pump, the corresponding measures such as blocking, flushing, cooling and filtering must be taken with reference to the relevant standards of the mechanical seal.

6) The mechanical seal shall be properly lubricated during installation. Ensure the installation dimension of mechanical seal according to the product installation instructions.

7) The equipment must be filled with medium before operation to prevent seal failure due to dry friction.

8) For the mechanical seal driven by a single spring in the sample, the spring rotation direction should be reasonably selected. Generally, from the static ring end, when the shaft rotation is clockwise, the right spring should be selected.
